SHELLAC-PACKAGE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that 1, BEN K. Form, a citizen of the United States,residing in Oak Park,

in the county of Cook and State of Illinois,

have invented a new and useful "Improvement in Shellac-Packages, ofwhich the vboth sides thereof. The coating 8 of copper following is aspecification.

My invention relates to sh of liquid orange used to market liquids iscomposed. bftin, or

more accurately a very thinsheet of-iron covered on both sides with tin-."Qonsiden able annoyance and loss has resulted from the use of vesselsof thissort forltm packaging of liquid orange shellacjiandcertain otherliquids which have been'fo-und to affected by contact with the tincoating for prolonged periods Where liquidorange shellac is package intin containers it has been found to lose his attractive orange color andto turn a dirty, muddy brown if left inthe container for the timenecessary to place it in the hands of the ultimate consumer.

.It is the principal object'of this invention to provide a shellacandequivalent package for the packaging and marketing of liquidorange-shellac and; the likeinwhich the contents may be left for anindefinite period Referring to the drawing-Figure 1 is a side elevatlonof a; container orvessel em bodymg my invention; Fig; 2 1s a verticalsectional View taken'substantially on the axis of the container shownii-Fig. 1; and Fig. 3 is an enlargedpartialsectional View takensubstantially on uie 1ine3+s of zFig. 1.

The container shown on the drawing is of a usual and well known type andconsists of side walls i, a bottom. 5, a frusto-conical top 6 and asuitable cork or, closure 7. The inner llac packages, providing for thepackaging andflshipping shellac and similar sub- L stances.'"=" 1 V Thecordinary sheet metal vessel-1hr] can surface of the bottom, side wallsand frustoconical portions, are coated with a layer of copper 8 (Fig.3).In the present instance the bottom,--"""s'ide walls and frusto-oonical"portions each consist of a central iron sheet 9 'and'a coating 10 oftin on the outer or on may be applied directly to the iron sheet 9 or tothe inner c'oating of tin.

I have found that copper has no appre ciable effect upon the qualitiesand properties of liquid orange shellac and similar substances, and itwill be manifest therefore Patented Feb. 29, 1916.

ish color given the shellac when packaged in I contact with tin. Thecopper coating may be applied either while the sheet metal is in uncutcondition, while it is in'the form of blanks or after the container hasbeen formed. .-An effectivev way of producing this internal coppersurface is to provide the copper in the form of a thin sheet or foil andto roll it with the body of the sheet-to be used to form the containerbetween heat-.

ed metallic rolls so that the'copper sheet or foil is substantiallysweated or soldered to either a surface of the iron sheet or to oneofthe sheets of tin covering one of the surfaces of the iron sheet. Itwill be obvious also that various changes may be made in the form,construction and arrangement of the parts without departing from thespirit and scope of the invention or sacrificing any of its materialadvantages, the form hereinbefore described being merely a preferredembodiment thereof. I i

I claim:

A commercial package comprising liquid orange shellac or the like'inclosed in a sheet metal vessel provided with a copper surface wherethe shellac comes in contact with the vessel. I
